On the NV-based quantum information lab bench,we need to apply a specific sequence of microwave RF pulse signals to the diamond NV center.In order to apply a specific sequence of microwave RF pulse signals to the sample,we use a slotline with the characteristics of low loss and no cutoff-frequency to design and implement a planar circuit radiation structure,which can efficiently modulate the microwave RF pulse signal into a microwave field and act on the diamond NV center to realize quantum state regulation.The design is based on the principle that the traditional slotline is used as the main transmission line and the T-shaped slotline is used as the power division structure,and the Ω-type ring is used as the radiation structure.A part of the power flow in the main transmission line is fed into the Ω-type ring to obtain a strong microwave field. Compared with the traditional lithography micro-nano process,this design uses the laser etching and electrochemical copper plating processes to achieve low-cost fabrication of the radiation structure.After testing by instruments such as network analyzer, the radiation structure has been applied to the NV quantum information test bench, and the alternating magnetic fields of about 4.48 Gauss and 48.49 Gauss are respectively obtained near the high frequency 2．8 GHz and low frequency 7.1 MHz operating frequencies.
